Hi everybody, I'm not seeing the X,Y and Z selection in the upper left of the edit window when using the Spin tool
I suspect that the tutorial you saw was created on a beta version of 2.80 before around March this year. Later betas and the release version (2.80.75) moved those settings to the right-hand properties sidebar. Press the N key then the vertical 'Tools' tab on the edge of the window to show the settings indicated in the image below.
